Conference Paper
Full-text available
Single photon counting hybrid pixel detector technology with short gate capability has been chosen to perform time-resolved pump-probe experiments in the energy range 5-15 keV at SOLEIL Synchrotron. The detector prototypes, based on the UFXC32k [1] readout chip, were developed for this initial purpose due to several very interesting performances of...
Conference Paper
Full-text available
Most basic and recent image edge detection methods are based on exploiting spatial high-frequency to localize efficiency the boundaries and image discontinuities. These approaches are strictly sensitive to noise, and their performance decrease with the increasing noise level. In this research, we suggest a novel and robust approach based on binomia...

Full-text available
The progress of wireless applications and traffic information increase magnetic noise pollution. That makes the signal restauration much difficult. This paper evaluated the problem of noise removing. We introduced some preliminary results of an approach for high noise level removing applied to sensor applications. It combined between time and frequ...
Conference Paper
Full-text available
Gaussian function has been frequently used in image and signal processing, especially on image denoising and edge detection. In this paper, we present an approximation model of the Gaussian function using the powers of a half-period of a sine wave. In the previous research, there is only exponential formulation of the Gaussian kernel with two param...
Thesis
Full-text available
The Nançay Radioheliograph is the only instrument dedicated to imaging of the solar corona imaging in the 150-450 MHz frequency band. It operates on the principle of interferometry, using 47 antennas essentially distributed on east-west (3.2 km) and north-south (2.5 km) axes. This study aims to explore a new technical concept for future radio astro...
Conference Paper
Full-text available
In both wired and wireless networks, time synchronization is an important service for a wide range of applications in distributed systems. This includes radio interferometry. However, literature researches show that many distributed protocols cannot satisfy sub-ns time synchronization accuracy due to asymmetric delay errors, accumulated jitters and...

In both wired and wireless networks, synchronization is an important service for a wide range of applications in distributed system, including interferometer radio. However, in the literature researches, many distributed protocols cannot be satisfied sub-ns time synchronization accuracy due to asymmetric delay errors, accumulated jitters and offset...

Technical Report
Full-text available
Ce travail entre dans le cadre d'une étude sur la conception d'un nouvel instrument dédié à l'observation de la couronne solaire, en particulier le système de numérisation. La caractérisation du numériseur est basée sur le Radiohéliographe de Nançay (NRH) actuel. La bande de fréquence analysée est comprise entre 150~MHz et 450~MHz, soit une bande p...

Question
Dear all, Mathematical models and theories are meant to provide efficient and accurate approximations of physical phenomenon. Some models have been ignored assumed to be true for hundreds or thousands years, few of them have been maintained and perfected to be close to reality (atomic models, the universe size, etc.). The human word perception and understanding is getting better every day. Also, most advances in science and technology are overlooked those of the previous cycle. However, these physical principles have been existed since the existence of the earth and the universe. The good news, Many theories and physical principles still exist and are just waiting to be discovered, our ignorance does not mean the absence of such a principle (Human limitation to exploring the earth against the vastness of the universe is a proof). Is there any mechanism or a technique which makes it possible to predict the existence of some new physical phenomenon, etc. or to initiate the reflection process ?. Thanks for your comments.
Question
Laplacian and gradient operators are often used to solve almost interesting problem in physics, such as wave propagation equations, heat equations, Navier–Stokes equations, etc. What is the intuitive interpretation of the Laplacian and gradient ? Thank you for your comments.
